To all whom t may concern:

Be it known that I JOHN F. BANNON, a citizen of the United tates, andresident of Bayonne, in the county ot Hudson and State of New Jersey,have invented certain new and useful improvements in Oil Burners, ofwhich the following is a specification.

rThis invention relates to an oil burner, and its object is theproduction of a burner, for liquid fuel, whereby the latter h-astransmitted thereto heat from the vaporizing agent before vaporizationtakes place. This is accomplished by making the outlet port of the steamchamber of a small cross area so that the steam therein will be held incheck. The oil chamber is adjacent to the steam chamber and thereby theoil in the former is easily heated. A detachable cap for the nose end ofthe burner allows the latter to be easily cleaned.

ln the accompanying drawings, Fig. l represents an exempliiication ofthe improved burner; Fig. 2 shows a section oi' Fig. l on the line 2, 2;Fig. 3 is a left hand end view of Fig. l; Fig. 4 shows a section of theburner as on the line 4, 4 of Fig. 2; and Fig. 5 represents a section ason the line 5, 5 of Fig. 2.

The burner is shown with the body portion 2O which has formed therewithat one end the exterior thread 21 and an opening with the interiorthread 22. The other end of said body portion has formed therewith thenose end 23 with the supporting rib 24. An oil chamber 25 in the bodyportion 20 at its outlet end has connected thereto the tapering outletport 26 and its inlet end 27 is threaded for oil supply piping notshown. An oil well 28 spaced Yfrom the oil chamber 25 is formed in thenose end 23 and at one end at the lower portion thereof connects withthe port 26. The oil well 28 at its outlet end terminates in thesegmental diverging outlet portion 29. A needle valve is indicated withthe tapered end 32, shank .33, enlarged threaded portion 34 and theoperating handle 35. A screw cap 36 engages the exterior thread 2l andhas an opening 37 which constitutes a guide for the shank 33. Thetapered end 32 can be seated on the tapered port 26 to either adjust thequantity of oil flowing through said port or to cut off the supply ofoil altogether.

A steam chamber 38 having the inlet opening 39 (threaded for steampiping not shown) at one end and the flange 40 at its other end isformed with'the body portion 2O over the oil chamber 25. A detachablecap or lip 4l has formed therewith the V shaped port 42. The latterconnects the steam chamber'38 and the top or the oil well 28.

F langes 43 and 44 are formed with the cap 4l. The flange 43 is securedto the flange 40 by means of screws 45 and the flange 44 is secured tothe nose end 23 over the segmental outlet portion 29 by means of thescrews 46 and forms with said portion 29 an outlet port for the burner.

ln operating the burner, oil is fed to the oil chamber 25 through inletend 27 and steam is allowed to iiow into the steam chamber 33, by reasonof which kthe oil in the chamber 25 will become warm and then Howthrough the outlet port 26 into the oil well 28. rIhe steam will be heldin check in the chamber 33 on account of the small cross area or" the Vshaped port 42. As the steam rushes through the port 42 it picks up oilfrom the oil well 23 and vaporizes it, causing the mixture or" vaporizedoil and steam to be discharged from the diverging segmental outlet port29 into the furnace for which it is used, in a diverging flat zone ofvapor.

The burner can be modified by dispensing with the needle valve andreplacing the screw cap 36 with a cap without an opening. therethrough.

Having described my invention what l desire to secure by Letters Patentand claim 1szl. In a burner for liquid fuel the combination oi a bodyportion with a nose end and having a steam chamber and an oil chamberadjacent one to the other, said nose end having an oil well spaced fromsaid oil chamber and having a port connecting it with the oil chamber, adetachable cap 'for said nose end covering said oil well and one end ofthe steam chamber, said cap having a port connecting the steam chamberand the top of said oil well, said cap forming an outlet port with theupper portion of the oil well 'for the burner, means to furnish steam tothe steam chamber and means to furnish oil to the oil chamber.

2. ln a burner for liquid fuel the combination of a body portion with anose end and having a steam chamber with an inlet opening, said bodyport-ion also having' an oil chamber adjacent to the steam chamber withinlet end and an outlet port, said nose end having an oil Well. spacedfrom the oil chamber and connecting et its lower end with vthe outletport o't the oil chamber, saidy Well having; a diverging segmentaloutletv portion, said Well at its top connecting' with e port in theburner leading to the steam Chamber7 the latter port directing a. flowof steam to the top portion of the oil Well7 causing' it to pick 11p oilfrom seid Well,

Vaporizing it and forcing the mixture of oil sind steam to be discharged'from the burner.
